Specification o Application filed 113311522;

To all whom it may COR/66m.-

Be it known that 1,,WI1JLIAM H; SnarnEAne, a citizen of the United States, residing at Portsmouth, in the county'of'i lort'olk and State of Virginia, have inventeda new and useful Water-Distilling Apparatus, .bf-i

which the following is a specification.

It is the object ofthe present invention-to provide an improved construction-of evaporator for use, chiefly, on board ship in purifying sea water, it being necessary, as Well the invention consists in the construction arrangement of parts shown in the accomw pass or convey the water to'a condenser after which it is introduced into the boilers.

With the above and other'objects in view,

panying drawings,- in which- Figure 1, is aivertical longitudinal s'e'ctional vi'ewthrough the evaporate, and Fig. 2 is-a view partly in side elevation and partly in section. I

r n the drawings, .theevaporator'is shown as comprised iii-pert of a drum. 5 which is preferably cylindrical andhas secured therein, at each end,*.a packingnnd spacing ring r- 6." alflie I drum -,,is furthefprovided, at each end, with aiheal 'the, head at one end of the drum b'eing indicated by the numeral '7 and? that at the other end ofthe drum by the int-- inera-l 8, both-heads being secured in osition.

Ietwo water chambers above described areronnwted by a. plurality of water fines 1 1 of the said: chambers and establishing bankof water lilies extends throughout an area equal to about one-half the area of the heads 11 and, as is clearly shown in Fig. '2

T-shapedbracingor strengthening bars 13 are securedupon the-opposing faces of the heads 11 of the two water chambers in and above the bank offiues 12 and connectbi urcated at each end to fit the outstanding brace barsiand having passed through their furcations and through the said outstanding ,flenges'ofvthe bars, seciiring bolts or other fastening devices 15 it being understood that ,by this construction the heads llof the wa ter chambers are firmly relatively braced fact: that the bank of fines 12 does not extend throughout the upper half'of the area of the heads. r ,"r Communication-is further established be- -'tweenthe water chambers, above the water ,line,.b '=rmeans of a pipe 16 which extends at bers, at' av point near the upper end thereof zand'alzicve the'watcn line, and the portions of thispipe ltd-'which'lie within thechambers "areforniedi each:.wi'tlr a plurality of' slots 17. andlare fitted each with a conical strainer 18a Whichiis 'referably of wire mesh rriateparallel reiationJvith" respect to each other these brace bars are tie'rods 14 each flange oftcorresponding ones of the T-shaped' botliiends into-the; respective Waiter cham-' chambers into whichtheseawater to be I 12 opening-at their ends through the heads communication between the same and thes of the drawings, this area extends throughout substantially the lower half of each head.

and at the weakened pointin view of 'the rial; its-state is conical in form, and isso arranged: within the respective end'o -the 'izpipe as to have itsmajor end fitting snugly withm the pipe and its-miner end terminatnermost one of thaseyeral slots 17 in. the

respective ends of!'. the pipes, words, these strainers 18 are fitted at' their itencc slightly great r-"than the distance between the innermost one of the several slots major ends into the end .of the pipe and pro jcct'inwardlyaxiall. ofthe pipe to a -dis;

ingiattaipoint directly inwardly of the'in- In other v and the adjacent ends of the pipe Leading or branching from the pipe 16 at a point intermediate of its ends and extending through the upper side of the drum-'5, is a branch pipe 19 from which lead other branch pipes 20, these latter branch pipes 20 extending to suitable condensers for the purpose of conveying the water vapor from the evaporator to such condensers where it is condensed prior to being fed into the boiler.

Opening into the drum 5 at the lower end or under side thereof is a steam supply pipe 21 having interposed therein a cut-off valve 22 it being understood that steam is sup- 7 for the purpose of indicating, to the attendant, the water level within the evaporator. There is also prorided,fi-n the said head 7 a peep window 25 through which the interior of the water chamber with which this head 7 is associated, may be viewed by the attendant. The head 8 of the other water chamber of the evaporator is provided at its'lower end with an opening 26 and closing this opening is a plate 27 and spanner 28.

In using the evaporator heretofore described, sea water is introduced into the Water chambers thereof until these chambers are filled to the proper de ree at which time the water level will be a ove the uppermost fines 12 of the bank of lines, the

' water filling all of the tines. Steam is then introduced into the drum 5 through the pipe 21 and circulates around the tines 12, ieating these fines and alsothe walls of the water chambers. lhis heating of the fines and the walls of the water chambers will result in vaporization of the sea water as will be readily understood and the water vapor will pass into the pipe 16 through both ends thereof and be conducted by way of the branch 19 and any one or all of the branches 20' to suitable condensers (not shown). It will be understood from the foregoing that in passing into the pipe 16 through the end thereof, the water vapor is freed of solid impurities by the strainers 18 inasmuch as it must pass through these strainers and the slots 17 in order to enter into the pipe 16. It will further be understood that the vapor as it leaves the evaporator, through the pipe 16 and its several branches, is free not only from solid par-.

each end of the vapor conductin g water lnlet opening into one chain er, and

ticles of foreign matter but also is free from saltand other impurities which ordinarily render sea Water unfit for use in the boiler. It will therefore be understood that the evaporator embodying the invention as heretofore described is particularly well adapted for use on ocean liners although its use is not limited to this particular relation 7 inasmuch as it may be employed in distilleries or in fact any place where it is necessary to purify water prior to use.

As the water is evaporated, the salt and other impurities contained therein are of course deposited in the water chambers and the tines 12 and may be removed therefrom whenever desired, by first removing the head 7 and then, after having removed the caked deposit of salt from the water chamber With which this head is associated, forcing the salt which has been deposited in the lines 12, through the fines and into the chamber with which the head 8 is associated and then removing the salt from this latter chambe.

through the openings 26. In this manner,

the evaporators may be readily and quickly cleaned and the arrangement of parts which permit of this ready and rapid cleaning is furthendesirable in that economy of space is so apparent, 'a maximum heating surface being presented to the action of the steam,

in a'minimum space. Furthermore, it will be understood that by forming the slots 17 in the ends of the pipes 16, a strainin area of maximum extent is presented an that for this reason, the water vapor may readily pass into the pipe 16.

What isclalmed is '1. In an evaporator, a drum, water chambers within the drum, water fiues establishing communication between the chambers,

and a vapor conducting flue establishingcommunication between the said Water chambers, a straining device arranged in flue, a

a steam inlet opening into the drum.

2. In an evaporator, a drum, heads removably see red at each end of the drum, water chambers extending inwardly from the said head, the said water chambers being free of connection with the heads, water fines establishing communication between the chambers, a vapor-conducting flue establishing communication between the said water chambers, a water inlet opening mto one chamber, and a steam inlet opening into the drum. p

3. In an evaporator, a drum, water chain bers within the drum, water fiues establish- 7 ing communication between the chambers, a vapor conducting flue opening at eaclrend into one of the water chambers and establishing communication therebetweerhf each end of said water conducting fiue 'being formed with a plurality of slots extending In testimony that I claim the feregein my .own, I have hereto afiixed my sit v 1 in the presence of two witnesse WILLIAM H.
